This cycling process is repeated as long as the ice detector remains in an icing environment. The ice detection system will detect and indicate icing when the airplane is on the ground. However due to the sensitivity of the ice detector probes, the ice detection system should be considered ineffective at airspeeds less than 30 knots IAS. crystal lynn bernard today

WebMar 1, 2024 · The optical ice detector works as a combined optical spectrometer and optical switch. A change in opacity registers as rime ice; a change in refractive index registers as clear ice. Modern ice sensors are generally lower in cost, lightweight and smaller in size. Relay contacts send a “go/no-go” or “ice/no-ice” signal to the host control … WebThus, the system is not activated until ice has accreted. Once the ice has been removed, the system automatically terminates, and awaits another ice detection trigger before cycling again. This is the de-ice cycle. Thermal Systems.
